ALARM CLOCK.

Application filed June 29,

To all 71, 7: 0m i'z': may 0012 0cm Be it known that JACK K. MC'WQ'FI, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, has invented rennin new and useful Improvements in Alarm Clocks, of which the following is a specification.

This invention relates particularly to alarm clocks and has more specific reference to alarm mechanisms therefor.

In conventional. types of alarm clocks now in use, the alarm mechanism embodies a single bell, and it has been found that when one gets used to the sound thereof, the alarm fails to have the desired effect of waking the user. It is accordingly an object of the present invention to provide an alarm mechanism embodying a plurality of members having different tones and operatively associated with the usual hammer, means being provided for manually moving the desired one of the members foremost into or out of operative relation with the hammer so that the sound produced may be varied from time to time and thereby avoid the above objection.

Another object of the invention is to incorporate the above desirable features in an alarm clock in such manner as to embody also the desirable qualities of durability and simplicity of construction as Well as case of manipulation.

lVith the above general objects in View, and others that will become apparent as the nature of the invention is better understood, the sameconsists in the novel form, combination and arrangement of parts herematter more fully described, shown in the accompanying drawings and claimed.

In the drawing, the view illustrates an alarm clock equipped with an alarm mechanism constructed in accordance with the present invention, the view being partly in rear elevation and partly broken a ay to reveal the alarm device.

Referring in detail to the drawing, in dicates the usual alarm clock casing in which is positioned the ordinary controlled alarm hai'mner including the head 6 mounted upon the vibrating arm 7.

A pair of" arcuate concentric members or bars 8 and 9 are mounted within the easing 5 for sliding movement through guides 10 in an arcuate path, suitable set screws 11 being associated with the guide heads for engaging the adjacent end portions of 1923. Serial No. 648,454.

the members 9 and 8 so as to eitectively retain the latter in adjusted position. It will be seen that the projecting free ends of the members 8 and 9 extend beyond the guides 10, and when the member-s8 and S) are slid therethrough towards the right, the desired ones both of the members 8 and 9 may be disposed with their projecting ends in a position beside the hammer head 6.

he other ends of the members 8 and 9 are attached to the intermediate portions 0t levers 12 which have inner ends PlVOtLllY mounted at 13 ata point inwardly of and concentric with the members 8 and 9, the outer ends of the levers 12 extending through circumterentially extending elongated slots, one of which is indicated at M, and being provided with mobs 15 outwardly of the casing 5 for conveniently swinging the levers.

As shown in the drawing, the member 9 is retracted out ofthe path of the hammer head 6 so that the same will not be operated upon by the hammer head when the latter vibrates, while the member 8 i slid through the guides 10 thereof sutliciently to project in a position beside said hammer head to be set by the latter. When this is disposed, a sound will be produced in accordance with the tone of the member 8. This sound may be accompanied by a different sound in accordance with the tone of the member 9 by simply releasing the set screw 11 of the latter and swinging the lever 12 thereof upwardly so as to bring the free end of the member 9 opposite the hammer head 6, after which the set screw is again tightened... Also, it is apparent that the set screw 11 and the guide for the member 8 may be loosened and the lever 12 attached to the member 8 and swung downwardly so as to retract the latter member out of the path of the head 6, whereupon the member 9 may be slid after loosening the set screw 11 associated therewith by swinging the lever 12 thereof outwardly so as to bring the projecting end of the memher 9 in the path ofthe hammer head 6 so that a single member of a different tone will be acted upon by the head 6.

t will thus be seen that l have provided simple and e'liicient means for rendering one or more of a plurality of members of an alarm mechanism operative or inoperative, whereby the tone of the alarm may be varied from time to time to assure such bene-
